How to clean your electronic devices

Cleaning cellphones

• The first step in cleaning your cellphone is to remove it from its case, preferably over a raised, flat surface like a kitchen counter, because phones out of their cases are more susceptible to damage if dropped.

• Blow into the portholes of your cellphone to dislodge any stuck dust or dirt. Then, mix equal parts rubbing alcohol and distilled water in a small spray bottle or bowl.

• Dampen a small part of the cloth with the water/alcohol mixture. Don't spray the mixture directly onto your phone, or it could seep beneath the glass screen or into the portholes and cause damage.

• Wipe all areas of your phone thoroughly, including the screen, taking care to trace any crevices.

• Lastly, wipe your phone dry with the remaining part of your microfiber cloth.

• Last but not least, you'll want to clean your case. If it's the sturdy plastic variety, you can clean it using the same materials you'll use for cleaning your cell phone. If you're the fancy type and your case is bedazzled with rhinestones or made of something more delicate, wipe it with a damp cloth and a tiny drop of dish soap or gentle cleanser appropriate to the material.

Sanitizing hand-held devices

Here are what you'll need to use for the safest way to clean your cell phone, remote control and smartwatch.

• A soft, microfiber cloth, not an abrasive paper towel that can scratch your screen.

• 70% isopropyl alcohol, commonly known as rubbing alcohol.

• Distilled water, which is less likely to leave mineral deposits and stains than regular tap water.

• A small spray bottle or bowl.

• Cotton swabs to reach into tight corners.

• Note: Do not use bleach or ammonia-based cleaners. They could ruin your screen.
